<p><P>PROBLEM TO BE SOLVED: To provide a gateway device capable of preferentially controlling a session in the state even though the gateway is connected to a network having an upper limit of the number of usable sessions. <P>SOLUTION: A gateway device 10 controlling sessions connected between SIP (session initiation protocol) terminals 21 to 26 and an NGN (next generation network) network 40 having an upper limit of the number of simultaneously connectable sessions includes: a session management unit managing each session connected between the contained SIP terminals 21 to 26 and the NGN network 40; and a session control unit determining if connecting the session corresponding to a session connection request generated from the NGN network 40 side to the contained SIP terminal on the basis of the number of connected sessions managed by the session management unit, a priority of each connected session; and the priority of the session corresponding to the session connection request. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
